Factory-direct OEM/ODM turnkey production. Explore our standardized high-demand contrast therapy, far-infrared, and hydrotherapy lines.
Bridging the gap between ultra-compact domestic setups and high-throughput athletic facilities through thermodynamic optimization and intelligent system monitoring.
The 0.5HP category represents the thermodynamic "sweet spot" for plunge capacities from 250L to 450L. Operating with low internal friction and variable-speed rotary pumps, our chillers achieve an exceptional Coefficient of Performance (COP > 3.2), mitigating heat dissipation and dropping recovery water down to a stable 2°C to 5°C even in 38°C ambient conditions.
Regulatory frameworks such as the EU F-Gas Regulation (EU 2024/573) and the US EPA AIM Act mandate phasing out legacy HFCs. Our 0.5HP ice bath systems integrate micro-channel evaporator coils engineered precisely for R290 (propane) and R32 hydrocarbons, maintaining zero ozone depletion potential (ODP) and ultra-low Global Warming Potential (GWP < 3).
Modern commercial purchasers prioritize self-contained bio-load sterilization. Dongda 0.5HP OEM chillers incorporate high-intensity ultraviolet (UV-C) quartz sleeves paired with precision 20-micron pleated multi-stage sediment cartridges and optional corona-discharge ozone injection, eliminating biofilm without compromising coil heat transfer.

Helium Leak & Hi-Pot Testing
Deploying vertically integrated manufacturing ecosystems to deliver cost efficiencies, component standardization, and custom mold tooling with minimal lead latency.
Robotic fiber laser cutting and CNC press brakes fabricate our heavy-gauge anti-corrosive galvanized and SUS304 steel external enclosures, ensuring IPX4/IPX5 water-resistance ratings.
Every chiller circuit is pressurized and tested using high-precision mass spectrometer helium detection, bringing refrigeration circuit failure rates well below 0.08% across high-seas shipping.
Sample batches endure stress-testing across 45°C ambient chambers and 95% relative humidity conditions, evaluating compressor thermal overload safeguards and electronic defrost logic.
Our OEM circuit boards support embedded Wi-Fi/Bluetooth modules, granting your brand an app-ready ecosystem for remote temperature scheduling, filter change alerts, and self-diagnostics.

Configured to satisfy international commercial protocols, local electrical codes, and rigorous physical operational parameters.
The optimal footprint-to-cooling ratio makes the 0.5HP chiller the primary selection for direct-to-consumer (D2C) brands bundling inflatable drop-stitch or acrylic tubs. Low operating acoustic levels (<52 dB) safeguard quiet residential ambiances while effortlessly maintaining 3°C cold plunge baselines.
High post-workout user rotation demands responsive heat dissipation. The continuous 1000 L/H pump circulation prevents thermal thermal layer stratification, chilling down bath volumes rapidly after consecutive athlete immersions.
Pairing 0.5HP chillers directly alongside far-infrared sauna blankets and steam boxes delivers complete hot-to-cold thermal recovery loops. Engineered with integrated self-priming pumps and GFCI plugs for safe client use.
Addressing compliance, production capacity, mechanical durability, and engineering configurations for professional buyers.
For standard 300L to 400L ice bath tubs, a 0.5HP compressor delivers an ideal pull-down rate (typically 2°C to 4°C per hour depending on ambient conditions) while drawing roughly half the wattage (550W vs 1400W). This keeps units compatible with standard 110V/15A household circuits in North America and 230V/10A domestic plugs across Europe without requiring specialized electrical installations.
We supply region-specific components built to UL 60335-2-40 (North America), CE LVD/EMC (Europe), SAA (Australia), and PSE (Japan) guidelines. Our factory performs 100% dielectric withstand (Hi-Pot) and earth leakage tests on the assembly line, equipping units with country-tailored GFCI/ALCI power cables.
Yes. We offer complete OEM sheet-metal tooling, bespoke rotomolded casings, custom Pantone powder coatings, and private-label silk screening. Our software engineering team provides API access or complete turn-key white-label iOS and Android smart control apps via Tuya or custom cloud protocols.
We provide a comprehensive 12 to 24-month manufacturer warranty covering core compressors, PCB boards, and pumps. We maintain a reserve stock of key modular spares (quick-connect fittings, UV-C replacement lamps, filter cores) and ship replacements directly via expedited international air freight to minimize downstream partner downtime.
